  • In thermokarst landscapes, permafrost thaw causes land subsidence with impacts on hydrology, ecology and biogeochemistry. Here, Olefeldt et al. produce circumpolar maps of thermokarst distribution, identifying that they cover 20% of the northern permafrost region, but store half the below-ground organic carbon.

  • Climate change strongly impacts regions in high latitudes and altitudes that store high amounts of carbon in yet frozen ground. Here the authors show that the consequence of these changes is global warming of permafrost at depths greater than 10 m in the Northern Hemisphere, in mountains, and in Antarctica.

  • Analyses of inventory models under two climate change projection scenarios suggest that carbon emissions from abrupt thaw of permafrost through ground collapse, erosion and landslides could contribute significantly to the overall permafrost carbon balance.

  • Peatlands are impacted by climate and land-use changes, with feedback to warming by acting as either sources or sinks of carbon. Expert elicitation combined with literature review reveals key drivers of change that alter peatland carbon dynamics, with implications for improving models.
